Subclaims¶

q2 i? Comparing four-year entrants to transfer students across graduation years and majors, only the bioscience 2000-2001 cohort (CLASP students) showed a statistically significant UDGPA difference (p = 0.0001), which the authors use to argue selection bias did not dominate the direct comparison. → Potter 2012

q2 · i2 · causal · r1

Cohort comparison using Table III: bioscience freshmen graduating 2000-2001 (UDGPA 3.098, n = 710) versus transfers (2.995, n = 491), p = 0.0001; the 1993-1994 bioscience and both non-bioscience comparisons were not significant (p = 0.65, 0.41, 0.09). The article prints no effect size.

"only bioscience majors graduating in 2000 and 2001 (those who took the CLASP series of courses) had higher average UDGPA's than transfer students in their majors and only for these two groups were the differences statistically significant (p = 0.0001)."

• Bioscience students who took the CLASP series had statistically significantly higher upper-division GPAs than students who took the traditional Physics 5 series — related
• Students who took the first quarter of CLASP before general chemistry earned significantly higher chemistry grades in all three quarters of the chemistry sequence — related
• CLASP students' expert-like epistemologies (MPEX-II) were statistically unchanged over the quarter, unlike the declines reported for most standard and many reformed physics classes — related
• CLASP students' MCAT Physical Science scores were slightly higher than Physics 5 students', but the difference was not statistically significant; Biological Science scores were identical on average — related
